Backing up Exchange

To back up Exchange data, you can select the following:

Symantec recommends that you select individual storage groups for backup rather than selecting individual databases in storage groups. Although you can select individual databases in a storage group for backup, the transaction logs for the entire storage group are backed up for each database selected.

For example, if you select four databases in a storage group for backup, the entire collection of transaction logs for the storage group is also backed up four times. The transaction logs are not deleted until a full backup is run on every database in the storage group. You can still restore an individual database from a storage group backup.

Note:

To perform incremental and differential backups of storage groups, or to perform a backup job for which continuous protection is enabled, make sure that circular logging is not enabled on the storage group.

Note:

You cannot back up databases to devices that are attached to a computer on which the Remote Media Agent for Linux Servers is installed.

To back up Exchange

  1. On the navigation bar, click the arrow next to Backup.

  2. Click New Backup Job.

  3. On the Properties pane, under Source, click Selections.

  4. View the Exchange data that you want to back up by doing one or both of the following:

    To display Exchange data on local or remote computers:

    Do the following in the order listed:

    • Click the domain name icon or icons that contain the Exchange installations

    • Expand the actual Windows computer icon that contains the Exchange installation.

    You must select the Exchange server name, not an IP address, in the backup selections list. Selecting an IP address for an Exchange server in the backup selections list on the media server is not supported.

    To display Exchange data from a server cluster:

    Do the following in the order listed:

    • On the virtual server, click the domain name icon or icons that contain the Exchange installations

    • Expand the actual Windows computer icon that contains the Exchange installation.

  5. Do one of the following:

    To select all Exchange storage groups for backup

    Check Microsoft Information Store.

    To select specific storage groups

    Expand the Microsoft Information Store icon, and then select individual storage groups.

  6. If prompted, select a logon account that you can use to connect to the Exchange Server.

  7. On the Properties pane, under Settings, click Microsoft Exchange.

  8. Select the appropriate options as follows:

    Backup method

    • (Information Store backups)

    Select one of the following backup methods:

    • Full - Database & Logs (flush committed logs). Select this method to back up the databases as well as their associated transaction log files. After the databases and transaction logs are backed up, the transaction log files for which all transactions are committed to the database are then deleted.

    • Copy - Databases & Logs. Select this method to back up the databases as well as their associated transaction log files. However, the transaction logs are not deleted after being backed up.

      You can use the copy method to make a full backup of a database without disturbing the state of ongoing incremental or differential backups.

    • Differential - Logs. Select this method to back up all of the transaction logs that have been created or modified since the last full backup. However, the transaction logs are not deleted after being backed up. The option to enable the restore of individual mail messages and folders is not available if you select the differential backup method.

      To restore from differential backups, the last differential backup and the last full backup are required.

    • Incremental - Logs (flush committed logs). Select this method to back up all of the transaction logs that have been created or modified since the last full or incremental backup, and then delete the transaction logs that have been committed to the database.

      To restore from incremental backups, the last full backup and all incremental backups done since the last full backup are required.

      See Snapshot and offhost backups with the Exchange Agent.

    If circular logging is enabled, incremental, differential, continuous protection backups cannot be performed.

    Continuously back up transaction logs with Backup Exec Continuous Protection Server

    Check Continuously back up transaction logs with Backup Exec Continuous Protection Server to enable a full restore of the Exchange database that includes transaction logs that are continuously protected between full backups.

    Before you check this check box, ensure that the Exchange server meets the requirements for configuring continuous protection.

    See Requirements for configuring continuous protection for Exchange data.

    See Best practices for continuous protection of Exchange.

    Make a recovery point that creates browsable backup sets and truncates logs every

    Check Make a recovery point that creates browsable backup sets and truncates logs every to create backup sets that you can browse from the Restore view. You can recover individual messages or folders from a point in time when the last recovery point was run. Each time a recovery point is made, it also truncates the transaction logs so that log growth is controlled.

    If circular logging is enabled, the recurring full backup of the Information Store completes without errors, but recovery points fail.

    If you do not check Make a recovery point that creates browsable backup sets and truncates logs every, then individual mail messages and folders can be restored only from the CPS backup.

    The default interval is 8 hours. The minimum interval that you can set is every 15 minutes. The maximum interval is 1 year. If you change the specified interval for the recovery points, the new interval applies after the next full backup or recovery point is run.

    Before you change the default interval, review performance factors for setting recovery point intervals.

    See About using recovery points to restore individual Exchange items to a point in time.

    Use Backup Exec Granular Recovery Technology (GRT) to enable the restore of individual mailboxes, mail messages, and public folders from Information Store backups (Exchange 2000 and later only; incremental backups supported with policy-based jobs only)

    Check this option to enable the restore of individual items from Information Store backups. Ensure that you meet the requirements for Granular Recovery Technology.

    See Recommended devices for backups that use Granular Recovery Technology.

    See About requirements for jobs that use Granular Recovery Technology.

    The GRT option is automatically enabled when you check the option Continuously back up transaction logs with Backup Exec Continuous Protection Server. The combined options let you restore individual items from a CPS Exchange backup.

    Perform consistency check before backup when using Microsoft Volume Shadow Copy Service (VSS) snapshot provider

    Select this option if you want a consistency check to be performed when the option Microsoft Volume Shadow Copy Service is selected. The option Microsoft Volume Shadow Copy Service is automatically used whenever a software backup is selected on the Advanced Disk-based Backup Option backup properties. You can also select the Microsoft Volume Shadow Copy Service on the Advanced Open File Option backup property page.

    The consistency check, which is run on the snapshot, determines if possible data corruption exists.

    If this option is selected, and the dependent option Continue with backup if consistency check fails is not selected, then data for specific Exchange objects that are determined to be corrupt are not backed up. All other non-corrupt Exchange objects are backed up.

    For example, if any transaction log file for a Storage Group is corrupt, then none of the transaction log files are backed up for that Storage Group when the Continue with backup if consistency check fails option is not selected. However, the Exchange database files are backed up if Backup Exec determines they are not corrupt. Similarly, if a specific Exchange database file is corrupt, then backup is skipped only for that corrupt database file. All other non-corrupt database files and transaction log files are backed up.

    When the option Continue with backup if consistency check fails is enabled, then all Exchange data is backed up regardless if corrupt files exist.

    See Snapshot and offhost backups with the Exchange Agent.

    Continue with backup if consistency check fails

    Select this option if you want the backup job to continue even if the consistency check fails. You may want the job to continue if you think a backup of the database in its current state is better than no backup at all, or if you are backing up a very large database that may have only a small problem.

    If Exchange 2007 backup source is LCR or CCR

    Select one of the following backup sources if the Exchange 2007 backup source is a CCR or LCR database:

    • Back up from the passive copy and if not available, try the active copy (recommended).

      When you use this option for a local continuous replication (LCR) or a cluster continuous replication (CCR) database, Backup Exec backs up the passive copy of the database by default. However, if the passive copy is not available, Backup Exec backs up the active database. During the backup, database performance degradation can occur.

    • Back up from the passive copy only (job fails if not available).

      Select this option when you do not want to affect the performance of the active database.

      If you select this option and the passive database is unavailable, the backup job fails. In this case, neither the active nor the passive database is backed up.

    • Back up from the active copy only (job fails if not available).

      Select this option to only back up from the active database.

      The active database contains newer information than the passive copy. Therefore, when you back up the active database, you have a backup of the most recent database data.

      If you select this option and the active database is unavailable, the backup job fails. Therefore, neither the active nor the passive copy is backed up.

      Note:

      You cannot back up the passive copy of the Standby Continuous Replication (SCR) database with Exchange Server 2007. The SCR is not available for backup selection.
